I've been looking for the same thing also.

I've emailed a couple of bumper manufacturers and am still waiting for a reply.

I wish I knew how to contact GM, and who to talk to. I'm sure these drawings are out there SOMEWHERE.

If anyone has any ideas, please, post em up.

Thanks,

Tim

not to highjack, but I was looking at this this weekend. The site was vague about exactly what was available. I was looking for dimensions to build bumpers and other similar items. Do you have any experience with this? The price tag is a bit steep if it doesn't give me the info I need.....

Thanks for anyhelp.

Check that link out.

It says that data is available for vehicles manufactured since 2002. However, some may go back as far as 1999.

Does anyone have a SEMA membership, and could tell exactly what all is on there? If the info I need is there, I'd gladly pay the membership charges. But I don't want to pay them for nothing...

Ok, after viewing the demo, it looks like you can put in a request for CAD files, if what you are looking for isn't available. So far, this is looking like the best bet for getting any OEM cad files.

If anyone has used this before, please speak up!

Thanks,

Tim

EDIT:

I just sent an Email to a guy listed as a contact for more information. I just asked him to verify that CAD data for the frame and front end was available for 88-98 fullsize chevy trucks and SUVs. Hopefully he will get back with me and I will let you guys know.

awesome Id love to see where this goes. I ran into the same thing about sema last week when I was looking for a CAD of an LS1 motor.

Another thought on getting a frame into cad.....I was shared a secret over the weekend....body shops have frame books/cds with frame drawings and measurements.....Ive already checked ebay, nothing. I want to call the manufacture but I havnt gotten around to it yet.

Well, I heard back from Gary w/ SEMA, and the guy that builds the Alien Patrol Bumpers.

Here's what Gary said:

Hi, Tim

Sorry, All the older Data at GM is removed from the servers to make room for the
Newer Data. Our GM Contact does not have access to the Older Data. We have a lot
of files of the 2003-2006 Trucks and SUVs for GM, and of course we have
everything available for the current models. If you have any questions, please
feel free to contect me.

Thanks

Also, the guy from Alien Patrol said that he didn't have any data on the older style Chevy trucks, which leads me to believe that he get's all of his data from SEMA.

So, it looks like we are out of luck on the older body style. I'm not sure if I'm going to pay $350 to join SEMA as a manufacturer just to get data for the newer trucks...

Maybe there is someone out there who kept the data from the older Chevy's?

Too bad its so expensive to have access to that CAD data. I wonder if they have the CAD for all the various engines out there. Engine mounts, etc would be so much easier to make from CAD files. I'm sure lots of people here would like to get there hands on some files for fabricating gnarly(technical term) vehicles.

I think I found what you're looking for. The GM upfitter web page has data going back to 1999. 1999 was a transition year so it lists current and new body styles. I'm guessing the frame didn't change much from 88 to 98 so hopefully this helps. The best part is it's all free. Here's the link:

Awesome! That's a huge help! I've not had much time to go through all of it, but it seems that everything is there. I'll spend some time tonight sifting through it all. I know that the 99 style suburban is listed on there, which was the same since 1995, so that will definitely help me out!

Thanks a bunch!

Tim
